Description

This man page describes the various (config) files and their formats used by the tin(1) newsreader. All files are expected to have unix style ('\n' aka LF) line endings.

$MAILCAPS
~/.mailcap
/etc/mailcap
/usr/etc/mailcap
/usr/local/etc/mailcap
/etc/mail/mailcap

mailcap(5) files as defined in RFC1524. The mailcap files are read by tin(1) to determine how to display non-text messages at the local site. Any line that starts with "#" is a comment. Blank lines are ignored. Otherwise, each line defines a single mailcap entry for a single content type. Long lines may be continued by ending them with a backslash character, "\".

Each individual mailcap entry consists of a content-type specification, a command to execute, and (possibly) a set of optional "flag" values.

The "type" field is simply any legal content type name. It is the string that will be matched against the ''Content-Type:'' header to decide if this is the mailcap entry that matches the current message. Additionally, the type field may specify a subtype or a wildcard to match all subtypes.

The "command" field is any UNIX command and is used to specify the interpreter for the given type of message. It will be passed to the shell via the system(3) facility.

Semicolons and backslashes within the command or any flag field must be quoted with backslashes. If the field contains "%s", those two characters will be replaced by the name of a file that contains the body of the message. If it contains "%t", those two characters will be replaced by the content-type field, including the subtype, if any. If it contains "%{" followed by a parameter name and a closing "}", then all those characters will be replaced by the value of the named parameter, if any, from the ''Content-Type:'' header. Finally, if the field contains "\%", those two characters will be replaced by a single "%" character.

Besides the type and command field the following "flags" are defined:

compose
The "compose" field may be used to specify a program that can be used to compose a new body or body part in the given format. Its intended use is to support mail composing agents that support the composition of multiple types of mail using external composing agents. As with the view-command, the semantics of program execution are operating system dependent. The result of the composing program may be data that is not yet suitable for mail transport - that is, a Content-Transfer-Encoding may need to be applied to the data.
composetyped
The "composetyped" field is similar to the "compose" field, but is to be used when the composing program needs to specify the ''Content-Type:'' header field to be applied to the composed data. The "compose" field is simpler, and is preferred for use with existing (non-mail-oriented) programs for composing data in a given format. The "composetyped" field is necessary when the Content-Type information must include auxiliary parameters, and the composition program must then know enough about mail formats to produce output that includes the mail type information.
edit
The "edit" field may be used to specify a program that can be used to edit a body or body part in the given format. In many cases, it may be identical in content to the "compose" field, and shares the operating-system dependent semantics for program execution.
print
The "print" field may be used to specify a program that can be used to print a message or body part in the given format. As with the view-command, the semantics of program execution are operating system dependent.
test
The "test" field may be used to test some external condition (e.g., the machine architecture, or the window system in use) to determine whether or not the mailcap line applies. It specifies a program to be run to test some condition. The semantics of execution and of the value returned by the test program are operating system dependent. If the test fails, a subsequent mailcap entry should be sought. Multiple test fields are not permitted - since a test can call a program, it can already be arbitrarily complex.
needsterminal
The "needsterminal" field indicates that the view-command must be run on an interactive terminal. This is needed to inform window-oriented user agents that an interactive terminal is needed. (The decision is not left exclusively to the view-command because in some circumstances it may not be possible for such programs to tell whether or not they are on interactive terminals.) The needsterminal command should be assumed to apply to the compose and edit commands, too, if they exist. Note that this is NOT a test - it is a requirement for the environment in which the program will be executed, and should typically cause the creation of a terminal window when not executed on either a real terminal or a terminal window.
copiousoutput
The "copiousoutput" field indicates that the output from the view-command will be an extended stream of output, and is to be interpreted as advice to the UA (User Agent mail-reading program) that the output should be either paged or made scroll-able. Note that it is probably a mistake if needsterminal and copiousoutput are both specified.
description
The "description" field simply provides a textual description, optionally quoted, that describes the type of data, to be used optionally by mail readers that wish to describe the data before offering to display it.
textualnewlines
The "textualnewlines" field, if set to any non-zero value, indicates that this type of data is line-oriented and that, if encoded in base64, all newlines should be converted to canonical form (CRLF) before encoding, and will be in that form after decoding. In general, this field is needed only if there is line-oriented data of some type other than text/* or non-line- oriented data that is a subtype of text.
x11-bitmap
The "x11-bitmap" field names a file, in X11 bitmap (xbm) format, which points to an appropriate icon to be used to visually denote the presence of this kind of data.
nametemplate
The "nametemplate" field gives a filename format, in which %s will be replaced by a short unique string to give the name of the temporary file to be passed to the viewing command. This is only expected to be relevant in environments where filename extensions are meaningful, e.g., one could specify that a GIF file being passed to a gif viewer should have a name ending in ".gif" by using "nametemplate=%s.gif"

tin(1) currently only respects the "test", "description", "nametemplate" and partly the "needsterminal" flags, all other flags are internally ignored. It also can't handle the "%F" and "%n" expansions yet.

Example:
# mailcap file example

image/*;\

xv -8 -geometry +0 '%s';\

description=%{name} %t-Image;\

test=test "$DISPLAY" != "";\

nametemplate=%s.IMAGE

message/rfc822;\

${PAGER:-"more"} '%s';\

edit=${EDITOR:-"vi"} '%s';\

compose=${EDITOR:-"vi"} '%s';\

print=a2ps '%s';\

needsterminal

/etc/nntpserver

default NNTP-server to read news from if not reading from the local spool. '-g server', $NNTPSERVER have higher priority (in that order), the default server given at compile time has lower priority.

${TIN_HOMEDIR:-"$HOME"}/.cancelsecret

secret to be used for cancel-locks if tin(1) is build with support for it. An empty secret file disables the cancel-lock creation in that case. This file should be readable only for the user.

${TIN_HOMEDIR:-"$HOME"}/.mime.types
/etc/mime.types
/etc/tin/mime.types

mime type / filename extension pairs

${TIN_HOMEDIR:-"$HOME"}/.newsauth

"nntpserver password [user]" pairs for NNTP servers that require authorization. If the password contains a space or a tab it must be enclosed in double quotes ("). Usernames must not be enclosed in double quotes and thus can't contain spaces or tabs. Any line that starts with "#" is a comment. Blank lines are ignored. This file should be readable only for the user as it contains the user's uncrypted password for reading news!

nntpserver
full qualified domain name of the news server.
password
user's uncrypted password for reading news.
user
username on the news server if it differs from the local login. This field is optional.
Example:
# sample .newsauth file
news.example.org secret
news.example.net arcane guest
news.example.com "top secret" james.bond@example.com

${TIN_HOMEDIR:-"$HOME"}/.newsrc

"newsgroupflag [article[,article | -article]...]" lines.

newsgroup
the name of the newsgroup.
flag
a flag indicating if the group is subscribed ':' or not '!'.
article
range of already read articles from that group; numbers separated by commas with sequential numbers collapsed with hyphens.
Example:
# sample .newsrc file
news.software.b! 1-666,669
news.software.nntp: 1-13245,13247,13249
news.software.readers: 1-19567,19571-19597
${TIN_HOMEDIR:-"$HOME"}/.tin/$NNTPSERVER${NNTPPORT:+":$NNTPPORT"}/.oldnewsrc

${TIN_INDEX_MAILDIR:-"${TIN_HOMEDIR:-"$HOME"}/.tin"}/.mail/

mailgroups index files

${TIN_INDEX_NEWSDIR:-"${TIN_HOMEDIR:-"$HOME"}/.tin"}/.news${NNTPSERVER:+"-$NNTPSERVER"}/

newsgroups index files

${TIN_INDEX_SAVEDIR:-"${TIN_HOMEDIR:-"$HOME"}/.tin"}/.save/

saved newsgroups index files

${TIN_HOMEDIR:-"$HOME"}/.tin/active.mail

active file ("mail_group_name maxnum minnum mailspool" quadruples) of user's mailgroups (requires tin(1) to be build with mh-mail-handling support).

mail_group_name
must be the pathname of the mailbox relative to field #4 with / changed to .
maxnum
just put a large number here, something higher than the highest message in the mailbox
minnum
put 0 here
mailspool
path of mail spool directory. This must be the full pathname to the root of the mail folder area.
Example:

Mail.inbox 12345 00000 /home/foo
Mail.outbox 23456 00000 /home/foo

This allows access to the 'inbox' and 'outbox' folders of user foo. They are accessed via /home/foo/Mail/inbox and /home/foo/Mail/outbox

${TIN_HOMEDIR:-"$HOME"}/.tin/active.save

active file of user's saved newsgroups, used by tin -R.

/etc/tin/attributes
${TIN_HOMEDIR:-"$HOME"}/.tin/attributes

The group attributes files may be used to override some global settings from ${TIN_HOMEDIR:-"$HOME"}/.tin/tinrc on a per group basis. Order is important as last match counts; this allows one to refine attributes for narrowed scopes. Note that the scope=<grouplist> line has to be specified before the attributes are specified for that list and each attribute can only be set once per scope section. All attributes are set to a reasonable default so you only have to specify the attribute that you want to change. All toggle attributes are set by specifying ON/OFF. Otherwise, they function exactly as their global equivalents. The following group attributes are available:

scope
This changes the list of groups to which the attributes that follow will be applied. See the section NEWSGROUP LISTS & WILDCARDS in tin(1) for the types of pattern that can be used here.
add_posted_to_filter
Identical to the tinrc variable of the same name
advertising
Identical to the tinrc variable of the same name
alternative_handling
Identical to the tinrc variable of the same name
ask_for_metamail

date_format
Identical to the tinrc variable of the same name
delete_tmp_files
If this is set to ON, then saved article files that have been post-processed will be automatically deleted, otherwise the user will be asked whether to delete the post-processed files. Automatic processing of marked articles using GroupAutoSave ('S') will suppress prompting.
editor_format

mark_ignore_tags
Identical to the tinrc variable of the same name
mark_saved_read
Identical to the tinrc variable of the same name
mime_forward
Determines whether usenet articles are forwarded as attachment or inline. When set to OFF, the forwarded article will be included in the body of the mail, while setting this variable to ON will cause the article to be attached as a separate MIME part. Enabling mime_forward is particularly useful for articles consisting of multiple MIME parts such as PGP/MIME signed messages or being encoded in a different character set than your local one. It is also useful if the receiver should be able to operate on the entire forwarded article (i.e., view or save it without your comments). On the other hand, if you want to forward only some parts of the article or to insert 'inline' annotations, you might want to disable this option. Currently mime_forward is forced if the article to be attached is a multipart MIME article, this may change in a future version. Please note that for this option to have effect, the tinrc variable interactive_mailer has to be set to 0 (which is the default).
mime_types_to_save
A comma separated list of MIME major/minor Content-Types that will be saved when using the view/save and save/autosave features. A single * can be used to wildcard the major and/or minor type and a ! as the first character in an entry will negate it, eg: image/*,!image/bmp,!text/html. Default is */*
news_headers_to_display
Identical to the tinrc variable of the same name
news_headers_to_not_display
Identical to the tinrc variable of the same name
news_quote_format
Identical to the tinrc variable of the same name

x_headers
A string including header-name and the contents of the header that will be automatically added when posting. If the string starts with a / or ~ then it is assumed to be the name of a file containing the header and its content to be inserted.

undeclared_charset
Assume (broken) articles without MIME charset declaration have this charset - default is US-ASCII. This attribute works only on systems with working iconv(3), others might have to compile tin(1) with --disable-mime-strict-charset.
Example:
# include extra headers
# assume ISO-8859-1 as charset if no charset is declared
scope=*
x_headers=~/.tin/headers
undeclared_charset=ISO-8859-1

# in *sources* set post process type to shar only
scope=*sources*
post_process_type=1

# in *binaries* turn on full post processing,
# remove tmp files and set Followup-To: poster
scope=*binaries*
post_process_type=2
delete_tmp_files=ON
followup_to=poster

# in fido.* newsgroups change quote_chars
# and add X-Comment-To: line
scope=fido.*
quote_chars=%s>_
x_comment_to=ON

# in *.test newsgroups, don't append signature
# and preset Subject
scope=*.test
sigfile=--none
x_headers=Subject: test - ignore - no reply

# assume ISO-2022-JP-2 as charset
scope=fj.*,japan.*
undeclared_charset=ISO-2022-JP-2

${TIN_HOMEDIR:-"$HOME"}/.tin/filter

The filter file is used to assign scores to certain articles. Based on the score an article can be filtered out (hidden) or marked hot. Empty lines or lines beginning with a '#' are ignored.

comment
Every entry (rule) in the filter file might get a comment. Multiple lines are allowed (but only for comments yet). Every line must start with the "comment=" keyword. Comments must appear first in the rule. Comment lines placed within a rule will be moved to the begin of the next rule. This might be changed in the future. Don't use '#' to mark comments as those lines are ignored and your comments will get lost on the next write of the file.
group
A comma-separated list of newsgroup patterns (wildmat-style) to which groups the filter rule will be applied. This line is mandatory!
case
0=case-sensitive, 1=case-insensitive
score
Score value of the rule; can also be one of the magic words "kill" or "hot".
subj
Match against ''Subject:''
from
Match against ''From:''. tin(1) converts the contents of the ''From:'' header to an old style e-mail address, e.g. ''some@body.example (John Doe)'' instead of ''John Doe <some@body.example>'', before trying to match the patterns in the filter rule.
msgid
Match against ''Message-ID:'' and full ''References:''
msgid_last
Match against ''Message-ID:'' and last ''References:'' entry only
msgid_only
Match against ''Message-ID:''
refs_only
Match against ''References:''
lines
Match against ''Lines:'', <num matches less than, >num matches more than.
gnksa
Match against ''From:'' address parser return codes.
xref
Match against ''Xref:'' line. Before any matching is done the line is turned into the same format ''Newsgroups:'' has that is it is turned into a comma separated newsgroup list with all other information (i.e. the article counter) removed.
time
time_t value when rule expires
Example:
comment=mark all articles about tin, rtin,
comment=tind, ktin or cdtin as hot
group=*
case=1
score=hot
subj=\b(cd|[rk]?)?tin(d|pre)?[-.0-9]*\b

${TIN_HOMEDIR:-"$HOME"}/.tin/$NNTPSERVER${NNTPPORT:+":$NNTPPORT"}/newsgroups

This file a copy of the servers newsgroups file which provides short descriptions of each newsgroup. It is automatically updated on startup except when using the ''-X''or ''-q'' command-line option and an old copy exists. Each line consist of two tab-separated fields "group.name one-line description".

group.name
is the name of the newsgroup
one-line description

extquote_handling
If ON quotes from external sources will be detected. Default is OFF.
extquote_regex
A regular expression that will be applied when reading articles. All matching lines are shown in col_extquote. If extquote_regex is blank, then tin uses a built-in default.

%%%
hide_uue
If set to 'No' then raw uuencoded data is displayed. If set to 'Yes' then sections of uuencoded data will be shown with a single tag line showing the size and filename (much the same as a MIME attachment). If set to 'Hide all' then any line that looks like uuencoded data will be folded into a tag line. This is useful when uuencoded data is split across more than one article but can also lead to false positives. This setting can also be toggled in the article viewer. Default is 'No'.
inews_prog
Path, name and options of external inews(1). If you are reading via NNTP the default value is "--internal" (use built-in NNTP inews), else it is "inews -h". The article is passed to inews_prog on STDIN via '< article'.
info_in_last_line
If ON, show current group description or article subject in the last line (not in the pager and global menu) - ToggleInfoLastLine ('i') toggles setting. This facility is useful as the full width of the screen is available to display long subjects. Default is OFF.

This option controls the processing and display of articles that are killed. There are 3 options, default is 0 (Kill only unread arts).

0
Kill only unread arts is the 'traditional' behavior of tin(1). Only unread articles are killed once only by marking them read. As filtering only happens on unread articles with kill_level set to 0, art_marked_killed and art_marked_read_selected are only shown once. When you reenter the group the mark will be gone.
1
Kill all arts & show with K will process all articles in the group and therefore there is a processing overhead when using this option. Killed articles are threaded as normal but they will be marked with art_marked_killed.
2
Kill all arts and never show will process all articles in the group and therefore there is a processing overhead when using this option. Killed articles simply does not get displayed at all.
mail_8bit_header
Allows 8bit characters unencoded in the header of mail message. Default is OFF. Turning it ON is effective only if mail_mime_encoding is also set to 8bit. Leaving it OFF is safe for most users and compliant to Internet Mail Standard (RFC5322 and RFC2047). Default is OFF.
mail_address
User's mail address (and full name), if not username@host. This is used when creating articles, sending mail and when pgp(1) signing.

maildir
The directory where articles/threads are to be saved in mbox(5) format. This feature is mainly for use with the elm(1) mail program. It allows the user to save articles/threads/groups simply by giving '=' as the filename to save to. Default is ${TIN_HOMEDIR:-"$HOME"}/Mail.
mailer_format

The format string used to create the mailer command with parameters that is used for mailing articles to other people. Default is '%M "%T" < %F' (e.g., /bin/mail "iain" < .article). The flexible format allows other mailers with different command line parameters to be used such as

sendmail -oem -t < %F
elm -s "%S" "%T" < "%F"
claws-mail --compose "mailto:%T?subject=%S&insert=%F"

interactive_mailer must be set adequate. The following substitutions are supported:

%Ffilename
%Mdefault_mailer
%Ssubject-field
%Tto-filed
%Uusername
%%%
mark_saved_read
If ON mark articles that are saved as read. Default is ON.
mark_ignore_tags
When this is ON, the GroupMarkThdRead ('K'), ThreadMarkArtRead ('K'), MarkThdUnread ('Z') at Group level and MarkArtUnread ('z') at Thread level functions mark just the current article or thread, ignoring other tagged, (un)read articles. When OFF, the same function presents a menu with choices of the current thread or article, all tagged, unread articles, or nothing.
metamail_prog
Path, name and options of external metamail(1) program used to view non-textual parts of articles. To use the built-in viewer, set to --internal. This is the default value when metamail(1) is not installed. Leave it blank if you don't want any automatic viewing of non-textual attachments. The 'V' command can always be used to manually view any attachments. See also ask_for_metamail.
mm_charset
Charset supported locally, which is also used for MIME header (charset parameter and charset name in header encoding) in mail and news postings. If MIME_STRICT_CHARSET is defined at compile time, text in charset other than the value of this parameter is considered not displayable and represented as '?'. Otherwise, all character sets are regarded as compatible with the display. If it's not set, the value of the environment variable $MM_CHARSET is used. US-ASCII or compile-time default is used in case neither of them is defined. If your system supports iconv(3), this option is disabled and you should use mm_network_charset instead.
mm_network_charset
Charset used for posting and MIME headers; replaces mm_charset. Conversion between mm_network_charset and local charset (determined via nl_langinfo(3)) is done via iconv(3), if this function is not available on your system this option is disabled and you have to use mm_charset instead. mm_network_charset is limited to one of the following charsets: US-ASCII, ISO-8859-{1,2,3,4,5,7,9,10,13,14,15,16}, KOI8-{R,U,RU} EUC-{CN,JP,KR,TW}, ISO-2022-{CN,CN-EXT,JP,JP-1,JP-2}, Big5, UTF-8 Not all values might work on your system, see iconv_open(3) for more details. If it's not set, the value of the environment variable $MM_CHARSET is used. US-ASCII or compile-time default is used in case neither of them is defined.
mono_markdash
Character attribute of words emphasized like _this_. It depends on your terminal which attributes are usable. See also word_h_display_marks and word_highlight.
mono_markslash
Character attribute of words emphasized like /this/. It depends on your terminal which attributes are usable. See also word_h_display_marks and word_highlight.
mono_markstar
Character attribute of words emphasized like *this*. It depends on your terminal which attributes are usable. See also word_h_display_marks and word_highlight.
mono_markstroke
Character attribute of words emphasized like -this-. It depends on your terminal which attributes are usable. See also word_h_display_marks and word_highlight.
newnews
These are internal timers used by tin(1) to keep track of new newsgroups. Do not change them unless you understand what they are for.
news_headers_to_display
Which news headers you wish to see. If you want to see _all_ the headers, place an '*' as this value. This is the only way a wildcard can be used. If you enter 'X-' as the value, you will see all headers beginning with 'X-' (like X-Alan or X-Pape). You can list more than one by delimiting with spaces. Not defining anything turns off this option.
news_headers_to_not_display
Same as news_headers_to_display except it denotes the opposite. An example of using both options might be if you thought 'X-' headers were A Good Thing(tm), but thought Alan and Pape were miscreants... well then you would do something like this: news_headers_to_display=X- news_headers_to_not_display=X-Alan X-Pape Not defining anything turns off this option.
news_quote_format
Format of quote line when posting/following up an article (%A=Address, %D=Date, %F=Fullname+Address, %G=Groupname, %M=Message-ID, %N=Fullname, %C=Firstname, %I=Initials). Default is "%F wrote:".

pos_first_unread
If ON put cursor at first unread article in group otherwise at last article. Default is ON.
post_8bit_header
Allows 8bit characters unencoded in the header of a news article, if set this also disables the generation of MIME-headers when they are usually required. Default is OFF. Only enacted if post_mime_encoding is also set to 8bit. In a number of local hierarchies where 8bit characters are used, using unencoded (raw) 8bit characters in header is acceptable and sometimes even recommended so that you need to check the convention adopted in the local hierarchy of your interest to determine what to do with this and post_mime_encoding.
post_mime_encoding
MIME encoding of the body in news message, if necessary. (8bit, base64, quoted-printable, 7bit). Default is 8bit, which leads to no encoding. base64 and quoted-printable are usually undesired on usenet.

thread_format

The format string used for the Thread level. Default is "%n %m  [%L]  %T  %F". The following substitutions are supported:

%Ddate
%Ffrom, name and/or address
%Iinitials
%Lline count
%Mmessage-id

1
Sum, the sum of all scores in this thread.
2
Average, the average score in this thread.
translit
If ON append //TRANSLIT to the first argument of iconv_open(3) to enable transliteration. This means that when a character cannot be represented in the target character set, it can be approximated through one or several similarly looking characters. On systems where this extension doesn't exist, this option is disabled. Default is OFF.
trim_article_body

Allows you to select how tin treats blank lines in article bodies. Default is 0. This option does not affect lines within verbatim blocks.

7
Compact mltpl., skip lead. & trai., 4 + 3
underscores_regex
A regular expression that will be applied when reading articles. All matching words are shown in col_markdash or mono_markdash. If underscores_regex is blank, then tin(1) uses a built-in default.
unlink_article
If ON remove ${TIN_HOMEDIR:-"$HOME"}/.article after posting. Default is ON.
url_handler
The program that will be run when launching URLs in the article viewer using PageViewUrl ('U'). The actual URL will be appended to this. Default is url_handler.pl %s.
url_highlight
Enable highlighting URLs in message body. Default is ON.
use_color
If enabled tin(1) uses ANSI-colors. Default is OFF.
use_keypad

use_mouse
Allows the mouse button support in a xterm(1x) to be enabled/disabled. Default is OFF.
use_slrnface
If enabled slrnface(1) will be used to interpret the ''X-Face:'' header. For this option to have any effect, tin(1) must be running in a xterm(1x) and slrnface(1) must be in your $PATH. Default is OFF.
utf8_graphics
If ON use UTF-8 characters for indicator ('->'), thread/attachment tree and ellipsis ('...'). Default is OFF.
verbatim_begin_regex
A regular expression that tin will use to find the begin of a verbatim block. Default is #v+
verbatim_end_regex
A regular expression that tin will use to find the end of a verbatim block. Default is #v-
verbatim_handling
If ON verbatim blocks will be detected. Default is ON
wildcard
Allows you to select how tin(1) matches strings. The default is 0 and uses the wildmat notation, which is how this has traditionally been handled. Setting this to 1 allows you to use perl(1) compatible regular expressions pcre(3). (see also perlre(1) and pcrepattern(3)). You will probably want to update your filter file if you use this regularly. NB: Newsgroup names will always be matched using the wildmat notation.
word_h_display_marks

Should the leading and ending stars, slashes, strokes and dashes also be displayed, even when they are highlighting marks?

0
no
1
yes, display mark
2
print a space instead
word_highlight
Enable word highlighting. See word_h_display_marks for the options available. If use_color is enabled the colors specified in col_markdash, col_markslash, col_markstar and col_markstroke are used for word highlighting else the character attributes specified in mono_markdash, mono_markslash, mono_markstar and mono_markstroke are used. Default is ON.
wrap_column
Sets the column at which a displayed article body should be wrapped. If this value is equal to 0, it defaults to the current screen width. If this value is greater than your current screen width the part off-screen is not displayed. Thus setting this option to a large value can be used to disable wrapping. If this value is negative the wrap margin is the current screen width plus the given value (as long as the result is still positive, otherwise it will fall back to the current screen width). Default is 0, wrapping at the current screen width.
wrap_on_next_unread
If enabled a search for the next unread article will wrap around all articles to find also previous unread articles. If disabled the search stops at the end of the thread list. Default is ON.
xpost_quote_format
Format is the same as for news_quote_format, this is used when answering to a crossposting to several groups with no ''Followup-To:'' set.

/etc/tin/tin.defaults

Yet another global configuration file with "variable=value" pairs. This one is for the more general options which usually can't be controlled via ${TIN_LIBDIR:-NEWSLIBDIR}/tinrc and/or ${TIN_HOMEDIR:-"$HOME"}/.tin/tinrc like resetting (to override the built-in default) the newslibdir.

${TIN_LIBDIR:-NEWSLIBDIR}"/"${TIN_ACTIVEFILE:-active}

This file lists the newsgroups that the local site receives. Each newsgroup should be listed only once. Each line specifies one group; within each newsgroup, articles are assigned unique names, which are monotonically increasing numbers.

If an article is posted to newsgroups not mentioned in this file, those newsgroups are ignored. If no valid newsgroups are specified, the article is rejected.

Each line consists of four space-separated fields "name highmark lowmark flags".

name
is the name of the newsgroup
highmark
is the highest article number that has been used in that newsgroup
lowmark
is the lowest article number in the group; this number is not guaranteed to be accurate, and should only be taken to be a hint. Note that because of article cancellations, there may be gaps in the numbering sequence. If the lowest article number is greater than the highest article number, then there are no articles in the newsgroup.
flags

can be one of those

y
local postings are allowed
n
no local postings are allowed, only remote ones
m
the group is moderated and all postings must be approved
j
articles in this group are not kept, but only passed on
x
articles cannot be posted to this newsgroup
=foo.bar
articles are locally filed into the ''foo.bar'' group
tin(1)
only tries to read the file if you read directly from the local spool, if you read news via NNTP, tin(1) uses the LIST (RFC3977) or LIST COUNTS (RFC6048) command instead.

${TIN_LIBDIR:-NEWSLIBDIR}/active.times

This file provides a chronological record of when newsgroups are created. It is normally updated by the local news server (e.g. innd(8)) whenever a new group is created. Each line consist of three space-separated fields "name time creator".

name
is the name of the newsgroup
time
is the time when the group was created, expressed as the number of seconds since the Epoch.
creator
is the electronic mail address of the person who created the group.
tin(1)
only tries to read the file if you read directly from the local spool, if you read news via NNTP, tin(1) uses the NEWGROUPS (RFC3977) command instead.

${TIN_LIBDIR:-NEWSLIBDIR}/newsgroups

This file provides short descriptions of each newsgroup. It is normally updated by the local news server (e.g. innd(8)) whenever a new group is created. Each line consist of two tab-separated fields "group.name one-line description".

group.name
is the name of the newsgroup
one-line description
is a short single-line description of the group
tin(1)
only tries to read the file if you read directly from the local spool, if you read news via NNTP, tin(1) uses the LIST NEWSGROUPS (RFC3977) command instead.

${TIN_LIBDIR:-NEWSLIBDIR}/organization

This file might hold a default organization to be used in the ''Organization:'' header. $ORGANIZATION has a higher priority if set.

${TIN_LIBDIR:-NEWSLIBDIR}/overview.fmt

This file specifies the organization of the news overview database (see also newsoverview(5)). The order of lines in this file is important; it determines the order in which the fields will appear in the database. See also overview.fmt(5). tin(1) only tries to read the file if you read directly from the local spool, if you read news via NNTP, tin(1) uses the LIST OVERVIEW.FMT (RFC3977) command instead.

${TIN_LIBDIR:-NEWSLIBDIR}/subscriptions

This file contains a list of newsgroups - one per line - which the client should subscribe to when the user has no ${TIN_HOMEDIR:-"$HOME"}/.newsrc for the news server. tin(1) only tries to read the file if you read directly from the local spool, if you read news via NNTP, tin(1) uses the LIST SUBSCRIPTIONS (RFC6048) command instead.
